IMPROVEMENT IN FANNING MELUE.

Specification forming part of Letters Patent No. 35,4092, dated June 3,155' To all whom it may concern:

Be it known that I, J noon MILLER, of Canton, in the county of Stark andState of Ohio, have invented certain new and useful In1- provements inFanning-Mills,- and I do hereby declare the following to be a full,clear, and exact description of the construction and operation of thesame, reference being had to the accompanying drawings, making a part ofthis specification, in which- Figure 1 represents a perspective view ofthe fanning-mill, and Fig. 2 represents a longitudinal vertical sectionthrough the same.

Similar letters of reference where they 00 our denote like parts of themachine in both of the drawings.

The nature of my invention consists, first, in the use of an auxiliaryriddle or riddle and shoe on the side of the fanning-mill for giving thegrain a second cleaning; and my invention further consists in combiningwith the auxiliary riddle or riddle and shoe a conducting-pipe as anair-passage from the fan-blower to said riddle or riddle and shoe; andit further consists in combining with the main rid die and shoe and theauxiliary riddle or riddle and shoe a conductor for transferring thegrain from the former to the latter to subject it to a second cleaning.

To enable others skilled in the art to make and use my invention, I willproceed to describe the same with reference to the drawlugs.

A A represents the sides of the fanningmill, and B the fan-case, whichineloses the fanwheel C. Connected with the fan -case there are hingedwind-boards D E, which can be adjusted by the slots and set-screws a b,so as to contract or expand the blast which passes to the main riddle F,or for changing the direction of the blast with regard to the riddle F.

i The grain from the hopper falls upon the directing-board G, and thenceonto the riddle F, the straws and coarser material being carried forwardonto the riddle by the fingers 0. The grain,after it has passed throughthe riddle F,drops upon the directing-board H,and is by it deliveredinto a trough or conveyer, d, in which a revolving armed shaft, 6, turnsfor carrying the grain onto the auxiliary riddle I, placed at the sideof the machine. This riddle I may have a shake motion given to it bymeans of the erank-wheelf and pitman g, and the grain passing over theriddle I is subjected to a blast brought from the chamber J, whichcommunicates with the fan-chamber by means of a pipe or trunk, II. Theframe or box or shoe in which the auxiliary riddle is placed may beadjusted at h to give it more or less inclination to cause the grain topass over it with greater or less rapidity, and when the grain arrivesat the end ofthe riddle I it drops upon the directing-board [,whiehcarries it to the desired delivery.

The fan is driven by a crank, j, and a pinion on the fan-shaft turns thebevel-gear k on the shaft Z, and the crank-wheel m on the shaft Zthrough the spring-pitman n vibrates the main shoe L with its mainriddle F,direetingboard, &c.

The fanning-mill, auxiliary riddle, and airconveycr may be so arrangedthat they can be transposed from one side to the other side of thefanning-null, so as to be operated from either side, and instead oftaking the blast from the main fan-blower to the auxiliary riddle aseparate fan may be used for this purpose.

This maehine may be built and used in corn neetion with thrashingmachines, so as to thrash and clean the grain in one continuousoperation, or for cleaning and separating thrashed grain, it beingapplicable to both operations,whetherjoint or separate.

Having thus fully described the nature and object of my invention, whatI claim therein as new is 1. In combination with the main riddle andshoe, an auxiliary riddle on the side of the fanning-mill to give thegrain a second cleaning, substantially as described.

2. In combination with the auxiliary riddle, a conducting-pipe orair-passage for introducing a blast to said riddle, substantially asdescribed.

3. In combination with the main riddle and shoe and the auxiliaryriddle, a conveying apparatus for bringing the grain from underneath themain riddle to the auxiliary riddle, substantially as herein described.

4. The so constructin of the fanning-mill and the auxiliary riddle asthat the latter may be used on either side of the machine preferred,substantially as described.
